Specification of Letters Patent.

Patented Aug. 30, 1910.

Application filed January 15, 1909. Serial No. 472,494.

in the groove of a wheel.

My invention is particularly adapted for placing theguide strip in a sprocket wheel used in connection with a driving chain, Such a wheel being fully illustrated and claimed in the patent granted to Frank J. Oake's, No. 905,744, dated December 1, 1908.

Referring to the accompanying drawings:-Figure 1 is a plan view illustrating my improved apparatus in position on a wheel; Fig. 2 is a side view of Fig. 1; Fig. 3 is the simplest form of the device; Fig. 4: is an enlarged section on the line 4-et, Fig. 5, with the pressing wheel in full lines; Fig. 5 is a section on the line 5 -5, Fig. i; Fig. 6 is a sectional view of the pressing wheel on the line 6-6, Fig. 4c; and Fig. 7 is a view of another form of the device.

A is the bad-plate of any ordinary form, to which is secured a spindle a, forming a bearing for the sprocket wheel B in the present instance; the wheel being held from turning by a pin a projecting from the bed-plate.

D is my improved apparatus for inserting the strip 0 in the groove b in the periphery of the wheel. This apparatus consists of two slotted arms D pivoted to the pina, one arm being on one side of the sprocket wheel and the other on the opposite side, as clearly shown in Fig. 2, and clamped to these arms D are bearings (Z.

The pivot pin 6 for the lever E passes through the bearings d and through the slots d in the arms D. Each bearing (l in the present instance consists of two plates clamped to an arm D by bolts (Z ,'so that the bearings can be adjusted longitudinally on the arms; the slots d being of suflicient length to allow for the adjustment.

Mounted on the short arm of the lever E-is a toothed presser wheel F and preferably mounted on theother arm of the lever is a handle by which the tool is operated. The teeth of the presser wheel F mesh with the teeth of the sprocket Wheel B, as shown in Fig. 1, and the presser wheel is preferablydmade as illustrated in detail in Figs. 5 an 6.

The part f of the presser wheel has a hub f upon which is mounted the part f and between these two parts is clamped a hard metal ring f by means of a nut 7, or other device; the .part of the wheel being held from turning on the part f by a key. The periphery of the ring f is preferably grooved, as shown, so as to accommodate the rounded edge ofthe strip to be inserted in the wheel.

To operate the device, one end of the strip a is pressed intov the groove a certain distance, then the. resser wheel F is located as indicated in Fig. 1, and by moving the lever E in the direction of the arrow it will cause the presser roller F to force the strip 0 into the groove 7;, as shown in Fig. 4; the arm being prevented" from turning completely on its pivot by the pivot pin e of the presser wheel coming in contactwith the arms D, so that when this pivot pin strikes the arms, the arms will move with the lever around the sprocket wheel, and as it moves .the presser Wheel will force the strip into the groove,-as clearly illustrated in Fig. 5.

It will be understood that the strip fits the groove tightly, so that considerable pressure can be exertedto force the strip into the groove and when once the strip is in the groove it will remain in position without fastenings.

lVhen there are a number of wheels of the same diameter to have the strip applied, then the presser Wheel F can be fixed directly to the arms D, as illustrated in Fig. 3. In this instance the lever is dispensed with.

In Fig. 7 I have shown the pivot pin 6' of the presser wheel mounted in the slots of the arms D and a lever E pivoted to the pivot pin 6. and provided with a stop pin 6 Thus it will be seen that by the use of the above described device I can roll a strip into the groove to form the guiding rib or flange of the wheel, and the pressure can be exerted to such a degree that the strip can be driven into the slot in such a manner that it will remain in position after it is once driven.

When the finished wheel is to be removed then one of the side bars is detached and the lever operated to back otf the roller F until it is clear-of the wheel, when the wheel can be withdrawn and another wheel placed operated to I claim 1. The combination in a devioe for press ing a strip into a roove of a toothed wheel,

of means for 1101 ing the Wheel i'n-a fixed position, an ann-adapted to be :pivoted at v'toothed- Wheel, of two'arms having longithe center of the Wheel, and a toothed pres'ser Wheel carried by the arm and; having an annular groove in its toothed periphery for the reception of the strip; the teeth of the resser Wheel being adapted to mesh-With the teethof the Wheel -in hiohthe strip is to be embedded.

2 The combination in a device for pressing a strip into the annular groove of a toothed Wheel, of means for holding the Wheel in a fixed position, an arm adapted to I be pivoted at the center of the wheel and to swing. entirely around said wheel, a grooved p'resserwheel carried by sa d arm and havingiteeth on eachsid'e of the groove 3. The combination in a device for tore v I ing a strip into a toothedlgrooved- Wheel, of an arm, a toothed grooved resser Wheel carried by thearimlsaid heel vbeing made up of two SGCtlOIlSSBlll'Gd together, and a ring less in'diameter thanthe Wheel clamped between thetwo parts.

4; The combination in a device for f0rcing a strip into the ahnularrgioove in a tud-inal slots. therein, a beanng carried by each arm, a pivot pin extending through the hearings and. through the slot'sin the arms, a lever mounted-on the pivot pin, and

a grooved resser Wheel on the lever having teeth adapted to mesh with the teeth of the Y first-named 'grooved' Wheel.

In testimony whereof, l have signed my name to this specificat on, n the" presence of two subsoribingwitnesses.
